I started with 25 rounds of chemo/rad, plan was surgery after that than folfox.They checked me 2 weeks after chemo/rad,had hard time finding the spot, thanks to ink mark, they found it, was cCR at that time. It’s been year since than.My hope was for cCR when all this started, and my wish got grunted.Did a lot’s of research, ask some questions members of this site that went through the same path, specially prs.If you are lucky one to be cCR, and opt for W&W approach,go for folfox after chemo/rad, or folfox than chemo/rad.Chemo/rad was piece of cake for me, hardlly any issuess, folfox was brutal.You can find a lot’s of usefull links on this board:
